These components are designated as ESDS (ElectroStatic Discharge Sensitive Devices). Handling ESDS boards: S The human body, working area and packing should be well grounded when handling ESDS components! S Electronic boards may only be touch by personnel in ESDS areas with conductive floor surface if - they are grounded with an ESDS bracelet - they are wearing ESDS shoes or ESDS shoe grounding strips. S Boards should only be touched when absolutely necessary. S Electronic modules and boards may neither come into contact with plastic materials nor man-made fibers S Boards may only be placed on conductive surfaces (desk with ESDS surface, conductive ESDS foam rubber, ESDS packing bag, ESDS transport containers). S Boards may not be brought close to data terminals, monitors or television sets. A minimum of 10 cm should be kept between the board and the screen. S Measurements may be taken on the boards only if viii - the measuring equipment is grounded (e.g. via the protective conductor) or - in the case of floating measuring instruments, the probe is briefly discharged before a measurement is taken (e.g. through contact with bare control housing).

The system is designed for hollow-shaft applications with 1FE1 and 1PH2 direct drives, but is also capable of operating as an autonomous spindle encoder. SIMAG H can be used with the following SIEMENS drive systems: S SIMODRIVE 611 digital S SIMODRIVE 611 analog (in this case, only in conjunction with the measuring wheel, pole number 2n) S MASTERDRIVES Design The SIMAG H measuring system consists of three components. S Sensor wheel S Sensor head with attached gauge holder plus 1 feeler gauge (0.20 mm) and 1 3x12 cylindrical pin S Fully pre-assembled cable module with 4 M 2.5x8 screws for mounting the flange-mounted socket and 2 M 3x6 screws for attaching the connector to the sensor head The sensor wheel carries a magnetic pitch as a fixed gauge. Various different inside diameters are available for each outside diameter. The inside diameter can be re-machined later if required. The sensor wheel is attached by means of the shaft nut or, alternatively, screwed to a shaft collar (not suitable for all sensor wheel variants). The sensor head scans the incremental and reference tracks on the sensor wheel by a non-tactile method and amplifies the output signals. The standard signal cables are connected via the flange-mounted socket on the cable module. This is fully pre-assembled and attachable to the sensor head. In this way, the measuring system can be optimally adapted to the prevailing installation conditions. Installation and mounting drawing 5-2. Dimension drawing, refer to 5-1. Siemens AG 1999-2002 All rights reserved SIMODRIVE sensor, Measuring System for Main Spindle Drives SIMAG H (PMH) - 07.02 Edition 1-13 1 General Information 07.02 Notice SIMAG H is a measuring instrument. The encoder system must always be installed by a qualified person. Any type of damage will impair the function of the instrument or render the system unserviceable. Leave the encoder components in their packaging until you are ready to install them! Please apply ESDS protection measures (refer to the Foreword). Disconnect the power supply before commencing with the installation. No liability will be accepted for any damage caused by improper handling of components. Output signals After installation and calibration, the measuring system supplies S two sinusoidal incremental signals of 1 Vpp in quadrature S one square-wave reference signal per revolution Note SIMAG H is compatible with SIMODRIVE motor measuring systems in terms of electrical signals and signal connector. The SIMAG H measuring system is scheduled to supersede the SIZAG 2 gearwheel encoder in the medium term and should therefore be considered for new spindle unit designs. Connection Pre-assembled signal leads are available for connecting the sensor to SIMODRIVE converters. See Catalog NC-Z and NC 60 for ordering information.

The sensor head must be screwed to the grounded metal assembly through a good electrical connection. The sensor head is adjusted using the feeler gauge provided. It is neither permissible nor is it necessary to make an adjustment using the encoder signals. The specified degree of protection of the encoder system is only guaranteed when the encoder connector is screwed into place. Before and during mounting, all parts and mounting surfaces must be free of any accumulated dirt. The tightening torques must be carefully maintained (refer to Fig. 5-2). Mounting steps Numbers in brackets, refer to the positions in Fig.5-2. 1. Insert the cylindrical pin (4) in the alignment bore of the bearing endshield (10). 2. Position the sensor head (2) over the cylindrical pin and very carefully press-in. 3. Insert the feeler gauge (5) into the gauge holder (3) of the sensor head; swivel the sensor head onto the sensor wheel. 4. Insert two screws (6) (M4, minimum length 12 mm) with two washers (7) in the threaded holes of the bearing end shield and slightly tighten. 5. Gently press the sensor head (2) against the feeler gauge and sensor wheel, tighten the retaining screws (6). Secure the screws so that they cannot be released. 6. Remove the feeler gauge (5) from the holder; the feeler gauge must be able to be easily withdrawn, however with slight suction, but without resistance. 7. Check the seating and state of the O ring seal in the connector (8) of the cable assembly on the encoder side. 8. Remove the gauge holder (3), insert the connector of the cable assembly (8) and tighten using the two M3x6 screws (9).

Remove any paint/varnish on mounting surface. To ensure fault-free operation, do not open the pre-assembled cable ends. Dimensions of the flange-mounted socket and mounting holes, refer to Fig. 5-1. EMC Guidelines Observe the general guidelines for correctly routing cables regarding EMC. Mounting steps Prerequisite: The sensor wheel and sensor head have been mounted. 1. Thread the connector of the cable assembly, on the encoder side, as well as the connecting cable for the motor temperature sensor through the mounting hole of the flange-mounted socket. 2. Insert the flange-mounted socket in the mounting hole and retain using the 4 M 2.5 screws provided (tightening torque, refer to Fig. 5-2). 3. Route the signal cable to the mounting location of the sensor head and retain using the 2 M3x6 screws provided (tightening torque, refer to Fig. 5-2). 4. Route the temperature sensor cable to the connecting terminal of the motor temperature sensor; if required, shorten and connect to the motor temperature sensor. The polarity must be carefully observed when connecting the temperature sensor cable! Refer to the Product Documentation of the motor manufacturer. The color of the cores and polarity of the cable: Refer to the connection assignment, flange-mounted socket, Section 3. Cable routing The following must be observed when routing signal and temperature encoder cables: S Route the cables so that they are not under tension S Do not route cables over sharp edges S Keep cables away from rotating parts and components S Securely retain in place S Carefully observe the permissible bending radii (refer to Section 3).
